When I launch emacs from the command line, I get the following message:
split-string: Wrong type argument: stringp, nil
As a result, when I try `EDITOR=emacs guix edit hello` it doesn't work.
I can confirm this is not a problem with guix edit, because when EDITOR=vim
it opens the package in vim.
(Joke about guix turning to the dark side goes here.)
Since I do not know if it is a problem with guix or emacs, I'm starting with
guix. It could be related to bug#38261
